Abstract: A cooking grill assembly adapted to be placed on the upper work surface of a barbecue heating unit. The grill assembly consists of two overlapping slotted plates, a grill component and an underlying drip pan component, releasably hinged together along one margin. The slots are offset from each other in such a manner that the molten fat dripping downwardly through the slots of the upper grill plate will be intercepted by the underlying drip pan plate and conveyed to a fat accumulation trough on the latter. The arrangement is such that the smoke and other combustion vapors can rise upwardly through the slots of both grill components and flavor the meat in the usual manner, without danger of igniting the molten grease resulting from the cooking operation.

Abstract: A solid, storage-stable, germicidal, pre-iodine composition comprises in dry admixture with each other a solid oxy-compound of iodine, a solid reducing agent for the oxy-compound of iodine, and a solid desiccant used in amount sufficient to combine during the storage cycle of the composition with ambient and/or endogenous water. The oxy-compounds of iodine are iodic acid, iodine pentoxide, potassium iodate and sodium iodate. Preferred reducing agents are ascorbic acid, dihydroxy fumaric acid, the thiol sugars and cysteine. A preferred combination desiccant and iodine solvating agent is polyvinyl pyrrollidone having a molecular weight of from 10,000 to 1,000,000.The composition is storage-stable for an indefinite period. Upon the addition of water, the oxy-compound of iodine is reduced to nascent iodine, which, in application, serves its well-known germicidal function.
